This website suggests four criteria, of which I would agree
that only "bilateral symmetry"
might...possibly...
argue for artificiality. Not many naturally
occuring geological features are bilaterally
symmetrical, so I'd be interested to see
somebody here at the BABB who knows
how take the Cydonia image and flip it in
a graphics program, see if it's bilaterally
symmetric.



I'm really sick of scrolling sideways, too, so
I'm adding carriage returns.

Electric Ashlar, if you could edit your post
and remove that humongous picture, you'd
get a LOT more responses in this thread.
A number of people are opening your thread,
seeing the Big Pic and the required PITA scrolling,
and are simply backing out again.
